I have a 2006 Mercury Grand Marquis w/ 64,000 original miles from original owner... just bought it. He had reciepts for $2,100 within the last three months. He said give me $2,800 and its your's... it is now mine. 😊

Simply Awesome! Thanks for sharing!

Sounds good. Now go get some after market neoprene sway bar bushings front and rear to tighten up the suspension . Another thing people overlook is changing your rear end lube. I live in the south where it gets hot, so get the ROYAL PURPLE 75W-140 lube.(if you live where it's hot) it has the friction modifier in it. Takes 2 1/2 qts. Drain it, clean it out real good and put a new cover gasket also. I painted my rear end cover before I reinstalled it (dark grey) and REPLACE your vent hose with 5/16 fuel line. That is very important. Do that and you'll be good to go brother....

Marty is great man 👍

I have been on the fence about tuning my 03 P71. Listening to the down shift, 1 - 2 shift, and how the engine sounded, I am no longer on the fence. Absolutely going to be calling marty up for this tune, I plan on doing some bolt on mods soonish for my full stage one, but I think the tune alone will be the most important step. I understand he has a package where you send the new specs and he sends a new tune when you make upgrades. assuming that is still the thing, I will be spending a little more but I haven't found anyone anywhere near his price for a proper effective tune that makes such a dramatic difference in the overall performance. I am also looking into getting my transmission modified, but once again, finding that special jmod confident individual seems to be difficult. THANKS FOR THE VID!

👍🏻😎 I have a 2006 P71. I need to get one of those for mine. Thanks for the video.

What type of paint is your vic? I'm trying to get something similar. Love the vic too ❤

Had a 97 Grand Marquis with a perf tune from 5 star, stock dual exhaust (was a single exhaust car) with Borlas, 3.73’s and the J mod done to the trans. It was a true sleeper. It was also lowered on LSC 16” wheels.

Best bang for the buck mods are tuner and rear gears, it came with either 2.73 or 3.27 I believe put some 3.73s or 4 10s it with leave harder if your not spinning but gas mileage is gonna go done ,you may also go with aluminum drives haft and lighter wheels for less rotating mass, but you may not want all that for a daily

ok so im definitely doing the jmod first, then some tune, any suggestions, for tuner shops? metro Detroit and surrounding areas

I have a 2003 Grand Marquis. Recently had the transmission redone. Engine runs perfect.. car runs great but burns a couple of quarts a month but that's okay. Still a smooth comfortable car. I wish we had an exhaust sounding like yours.

If by the run button, you mean secure idle (press a button and leave the car without the keys in but the engine on) most cop cars get that removed after service, or surprisingly a lot never have it in the first place, and just get left with the keys in the ignition. I made by own secure idle and installed it, it was quite easy.

How do i get a marty tune? I am new to the platform picked up a 2003 gs today :) thank you

Just got a 93 tune for my 07 f150 with the 4.6 and I can say with 100% certainty that Marty is no joke.

What kind of Exhaust u got installed?

I've got a 2007 crown Vic,too. Mine sounds almost exactly like your's driving in it's stock tuning. Feels like it's in overdrive for too long sometimes but not doing much besides driving in 2500 rpms. Maybe i should try out Marty tune,too

Diablo Tune 93 on a 2005 Crown Vic police interceptor. She definitely peeled the tires with a 1.5 turbo on it at Norwalk Raceway.

Those are a couple upgrades that will not break the bank and make your car handle a lot better and you won't have to worry about any rear end whine or overheating.....

Sharp paint job i like it a lot

Thanks for sharing! I am considering the Marty Tune for my 2011. I like the car a lot but it could use more pep. Mine is 100% stock.

its like im looking at my own car

Run premium fuel. Having the boost added, it's mandatory. Or you risk chipping pistons from donation issues. There's a big passability that your ECM is detecting KR and pulling timing. That'll rob you of a lot of power. Not familiar with that tuning platform you're using, but with HP Tuners you can use the scanning software program to check for KR and do a lot of other custom tuning. It's what I've been using for a few years now. That thing you're using reminds me of one of those hypertech tuners that has pre programmed canned tunes.

I got a marty tune for my 2000 Grand Marquis and I had to have him change a few things, mainly the wide open throttle shifts and shift firmness. Side note, he seemed upset that I wanted a few revisions until I got what I wanted. Don't let that dissuade you from getting the tune you want. You paid $535 for it. Anyway, it would shift out of first at like 60mph at WOT, which was ridiculous. If I hadn't had him change that, it would have eventually destroyed the torque converter. I asked him to lower the 1-2 shift to 4800rpm with transmission firmness to 6. I set the transmission firmness to +5 with the tuner and now it's perfect! Dosn't look like much on camera but it feels a lot better in person. Is it worth $500? Depends on how you feel after buying it. I had the money to spare and I enjoy driving it now more than ever so I'm satisfied.

My fuel pressure regulator was clogged with rust and had a tear Fixed the problem you are mentioning

Just came across your channel and this clip, overall now with this much time has passed is it still acting well with the tune?.

that cornering and power cut has happend to me for 3-4 years ..then my trans went out, got a rebuild and no more taking a corner and the trans lagging..i always thought this was a safety/fuel issue but nope...trans is worn and goin out. Same symptoms with low trans fluid

Thanks for sharing this video, what's the setup for the exhaust? Trying to match that on my 04 Marquis

Is there a website for this tune?

My 05 MGM does that hiccup. I think it’s my stall converter

i have the programmer like yours how do i get it to the person to load a Marty Tune please and thank you

I got the same radio in my Crown 😂 pioneer

What kind of exhaust do you have? Sounds great

An illinois Vic cool..

I wanna buy a crown Vic as a first car, any tips on years or models to look out for?

I just bought a 2000 crown vic off my buddy that has the exact same tuner and every time it shifts into third on the 87 tune and shuts down every light on the dash for a few seconds

Where did you find your center console/arm rest?

those 4-2 shifts hurt dont do that it slipped each time dude

Love the color on this vic. Is it baby blue or light gray? Looks really unique

do you have to keep it plugged in ?

What center console you use

Did you have lag on takeoff before the tune? Due to electronic throttle (drive by wire) I hear that’s why my 08 does it. Does getting the tune help with throttle response on takeoff? That is my least favorite part about my car

you can get better shifting with a J Mod drill the 10 hole to the larger size reconned remove both lower sprigs on the 3/4 accumulator and the stiffer lower spring on the 1/2 accumulator the cost is the fluid a drill bit and your time it will shift as good or better also get the Uhaul pan with plug while you have it off for easier maintenance in the future the rest of thee "performance benefits" aren't worth the added cost IMO

super pretty area you're driving thru

Dude what is that exhaust system?

ah i see your crown vic also abs issue too.

The main reason for the lag is you have throttle by wire where throttle by cable is 1000 times better. The throttle by wire is controlled by the computer which gives the delay

I have a 06 can I get this with a completely stock interceptor and it won't mess up anything like transmission or blow my engine

Does this move the 4k rpm limiter up? Or no

Southern illinois by stl area. Wya

Does it get better or worse gas mileage MPG

You might still have taller gears. Some P71s had 3.55 gear set. Yours may have the 3.27 or even the 2.73 highway gears. I put a 3.73 set in my LX Sport and the car responds much better but still only 2300 RPM at 70 and 23 MPG or better if I baby it.

Add turbo 108 from oreillys then retune it to 93 youll notice so much more

Is the parking brake on?

Ive owned a 2007 P71 and its a good car. But honestly a 03-04 way better

I can't see $500. I just don't get it. I can see $100. It is just computer programming. I wonder if you can do 2 cars with that box?

Does it give you better gas mileage

All of this video is subjective, would of been nice to see 0-60 stock and with tune.

How it was stock lol bro it’s stock come on now

My car stock was way better then yours, mine is also not a p71. I have single exhaust with a cherry bomb and it still looks better then your car stock. My ecu went bad with the pats system so I got a p71 ecu and it now shifts right at red line and bangs shifts, from every video I've seen my car is a lot more awake then most crown vics. That being said in the year or so the car is getting a turbo and if it doesn't it will be getting a marty tune.

Just buy a faster car. Daily drive these, own two cars. Jaguar XJ8.

Do you have to leave it plugged in after the tune is done?

what kind of exhaust do you have on there? sounds awsome.
